Reaction Steps

10 g (60mmol) of sulfanilamide are suspended in 150 ml of dioxane and 4.6 g (60 mmol) of pyridine are added. 12.2 g (60 mmol) of 2,4-dichloro-benzoyl chloride are then added at 0° C., and stirring is continued for 2 hours at room temperature. The mixture is stirred in 200 ml of water, and the precipitate which separates out is filtered off with suction and dried;
